Specication forming part of Letters Patent No. 34,270, dated January 28,1862.

.To all whom it may concern.-

Beaknownthati, WILLIAM ROMANS, of O6-- lumbus, in the county of Franklin and State of Ohio, have inventeda new and useful Improve' ment inv Locomotive Railroad-Cars; and I do hereby declare thatthe following is arfull,

clear, and exact description of the same, refer-' ence being had to the accompanying drawings,

forming part ot' this specification, in Whichq Figure l'is a side elevation of my improved f locomotive-car. Fig. 2 is a vertical longitudinal section of the same. Fig. 3 is an'inverted plan of the same. Fig. 4 is a broken:

plan view of the -rear truck of my improved locomotive-car.

Similar letters ot' reference ineachof the several igures indicate corresponding parts. `The nature of my invention consists in the t adaptation and use of 'a locomotive engine which has a horizontal locomotive-boiler and a horizontal water-tank, in combination with long accommodation or longr freight cars spe-- cially adapted for the vsaid-engineI in such' manner that the front o f the car has its support on andA at or near the center .of the locomotive-truck frame and turns horizontally'at said point, and at the same time the'boiler, water-tank, locomotive-truck frame, and. all

'other connections of Ythe locomotive are free tomove round in the path of a horizontal circle in turning curves ot' railroad-tracks.

It consists, second, in so arrangingthe watertank, locomotive-truck frame, engine-cylinders, and valves of the locomotive adapted for sustaining the front of'a long car that the eccentrics, link-motions, and valve-rods are located between the truck-frame ,and the innerl faces of the driving-wheels', and thus a locomotive of great compactness, particularly adapted for thepurpose to which I apply it,

is obtained.

yIt consists, third, .in so arranging the rear truck on along oar that it is capable ot being moved while'the car is resting upon it a y greater or 'less distance' toward the locomotive,

and the long car thus enabled to turn short or sharp curves or corners with great ease and safety, and also adapted for beingA moved round on the small turn-tables provided for locomotives and short cars in Ordinary use.

` To enable others skilled inthe art to make and use my invention, I willproceed. todo scribe its construetionand operation.v

In carrying out my invention I adopt an ordinary long car A, known amongv railroad men as long accommodation passengercars, and separate about one-seventhof its length, Vat the front end, from the main portion, bymeans of a transverse Avertical parti- C for the engineers to operate in 'and for car'- rying fuel.v

motivefboiler, leaving sont Kentro'om for vibrating and curving. Under the front end of the `flooring ofthe engine-room ,a strong iron bolster G is screwed so as to be readily removed. This bolster has the head of a ylringl pin E fastened firmly in it; On each side of`v the central opening wheel-housingsA a a' are provided.l said housings being tormedby ciitting apertures through thefiooring ofthe en- .gineers room and arranging boxes, which are hollowed in form ofja segment, over lthe/same, asshown. D, y

At the rear end Ot' the riool-ing or theicar, on the under side, a strong bolster J is screwed or bolted, and through this bolster and the .iiooringoiv the car -a'hing-bolt passes.

From' the bolster at thepoint where ,the king-- holt passes through it, a cylindrical stop or projection h extends downward, for a purpose hereinafter described, and from the bolster toward the front of' the car rails L L extend a suitable.distancesay, about to the center of the length of the car-said 'rails being at attached firmly to theunder side of the doorn ing of the car, as shown.- ,Artl the center of.

the ,length ofA the cara transverse windlassshaft M is placed, the rails serving as-its bear? ings. This shaft has a chain' 'or'l rope' N atv tion B, and thus -forni a small separate rooie. v

In the `looring of this vroom isf cut alongitudinal opening 1), which extends,

circular under. portion of the horizontal loco-- tached tol-it, the 'rope being long eno'itgh. to.

` swinging v Sand water-tank F, said parts beingarranged upon and firmlytastened to it. 'The cylindrical portions of the boiler-runs horizontally above the frame of the truck andzextends back and connects to the dome and arch 4of the fire-box. The fire-box passes down inside of thetruck-frame infront. of the hind axle thereof. The water-tank occupies a horizontal position within the truck-frame directly under the boiler and yforward of, the {ire-box. On the locomotive-truck two engine-cylinders `T ,'l", with steam-chests on their inner sides,

are also arranged. 'These cylinders are 1ocated onthe outside of the truck-frame, and the rods b band eccentric's c c, which actuate the valves of the steam-chests, occupy positionsoutside ofthe truck-frame between theinner faces o the driving-wheels and the side bars of said frame, while the piston-rods are arranged-outside of the driving-wheels. This arrangement of the parts economizesspce' and giv'es the whole space within the truckframe for tank-room and also places the ec- `centrics in protected positions and convenient for being manipulated; The tank is supplied with wat-er by means of a man-hole v at its front end, and the water from the tank to the boiler may be conveyed by means such as are commonly used-wiz., pipes d e anda pump f-which are-to be so arranged as to loe-'capable of being thrown in and out of operation at the will of the engineer. The rear truck Ris very similar in construction to the. trucks ordinarily used to supportv cars. Its swinging'beam, however, has attached to its top a king pin plate V with a horseshoe` shaped flange 'i projecting -up round the kingpin hole, which is formed in the plate and beam, On each side of this plate grooved rollers W W are provided, lsaid rollers .being so located and arranged that they move longitudinally, while their su-pports swivel horizontally, and when the truck is applied to thev car they receive the rails which are on the'botto'm of the car.

The car and trucks thus constructed are i connected as follows: The removable bolster with king-piu attached and the fender at the front of the car are detached, so as-to admit the lire-box and a portion o the boiler of the locomotive-truck into the engineers room. The locomotive-truck is then backed up under the front endet the car, which at this stage held elevated for the purpose by a jack-r screw or .other means. Before the locomotive is backed 'u p theking-bolt is adj usted to its hole in the water-tank or in beams of .the lozontal circle.

comotive-truck frame,

the bolster which carries the pin resting transversely on said frame. The fire-box and dome portion of the boiler enters the engineers r'oom through the door and the opening in its flooring and is kept in positionby means of the king-bolt. Round the re-box are provided india-rubber aprons j, which overhang the ooring in such manner as to close the openings in the flooring around the tire-box or leg of the boiler and still allow the necessary vibrations and curvings.' The removable fender and bolster are now fastened in their original positions to form the connection between the car and the locomotive, and lthat connection is such that no part of the locomotive is a fixture with'the car, but every part is free tomove independently of it, except so far as the lo- 'comotive and the car are connected bythe king-bolt.V =Thus the locomotive and all its attachments are permitted to move round curves and corners in the path of a horizontal circle without being subjected to any otl the strain which is due to the center or king bolt. By having the fender and bolster removable the locomotive-truck,with all its attachment-s, can at any moment be run out from underthe' end of the car, andby using a horizontal locomotive-'boiler the water-tank and doctor-pump can be so disposed. that an exceedingly small space serves for accommodating them, and, further, no strain which is due to the center-pin comes upon the Waterltank, boiler, orlany of the parts necessarily used with a locomotive, as all the parts are wholly supported by the truck-frame. The engineer also is comfortably housed and nearly the rear half ofthe locomotive is covered bythe flooring of the engineers room,- and the center of motion on which the engine depends is brought to or near the center of the locomotive-truck frame linstead of being located at the extreme rear end thereof, and therefore the locomotive can turn much shorter curves, it only having to sweep the -circle withv one-half its length. It will also be seen that the rear portion of the engine is brought very coxnpactly under the front part of the car as the hind wheels extend up into the housings a considerable distance,

said housings being'wide enough to allow the necessary movement in the path of a horiha'vig been thusconnected to the car, the rear truck is run under the rear end of the car and fastened by the kingbolt. When the connectionis thusformed,thehorseshoeange has its open end in rear of the king-pin, and the windlass-cord is hooked to one of the cross-beams of the truck. The car is now ready for use. 1

, In the use of the car it often becomes n'ec essary, in ord er to turn it completely round or sweep it round sharp corners or curves, to move the rear truck to the center of the length o'f the car. To accomplish this, withdraw the .king-bolt and wind Iup the wiudlass-cord by The front locomotive-truck means of thecrank and windlass shafts. Thus winding up the cord draws the truck under the rails on the bottom of -the car to the desired position. 'When in said position, the longitudinal motionvof the rollers and the horizontal. swiveling motion of their bearings allows of the truck tnrningcrves, saidrollers and the rails maintaining theconnection, and the bearings of the rollers serving as the axes of motion to the truck. To get the truck back for direct connection with one anotherin such manner that all the connections of the 1ocomotive are free to turn independently of the car, and that the weight of the front end of the car rests centrally or nearlyvcentrally on the locomotive-truck, and thus is made available for steadying the locomotive on the track, while the center otmotion of the locomotivey is transferred from the rear end to the center l of the truck, all as and for the purpose ,set fOI'h; l

2.E Making the front bolster G- and also the fender E-removable, substantially as and for the purpose setforth.

3. In combination with the construction and use of the devices as set forth in the iirst claim, the manner, substantially as herein described, of arranging the valve-rods, link-motions, and the eccentrics between the inner faces of the locomotive driving-wheels and the outer sides of the locomotive-truck frame, for the purpose set forth.

4. So constructing and arranging the car and the rear truck and connecting the same that the truck while the car is resting upon it may be moved a greater or less distance toward the locomotive, and vvhen thus moved shall be free to turn curves, substantiallyas and for the purpose set forth.

5.. The combination of the flanged plate V 'L' of lthe rear truck and the tubular tion h of the rear bolster J of the car, sub# stantially as and for the purposel herein described.
